The following XAML code snippet uses an Image object to display an image. The OpacityMask property of an element (defined in the UIElement class) is used to apply an opacity mask on an object such as a Rectangle or an Image. Generating and Printing Surface IdentityTag Opacity masks allow us to make portions of an object transparent or semi transparent.Changing the Orientation or Surface application.Here is an example of an ellipse with only its top right quadrant being visible. not always, the lesser number elements in your visual tree = faster the rendering time which equates to better perf leading to happier customers :). This is what you were trying to do in your post.Īs a general rule of thumb, i.e. inclusion and exclusion of visible regions, is all what you are interested in then you can do it with 2 elements. The above solution uses 5 visual tree elements inside an image to achieve what you were trying to do. I had posted an elaborate lengthy reply a moment ago but it has disappeared since. I suggest one use clip bounds for inclusion and exclusion of visible regions and opacity for a "fade" effect inside those regions. Yes it is certainly possible do it without an opacity mask. OpacityMask is very much useful in giving awesome look and feel to your application like glass effects transparency etc…To understand better about the opacitymask I will be writing another post which talks about creating a magic transparent glass. This is the basic idea of OpacityMask.I will get confused often while working extensively with OpacityMask.So if anybody reading this, have more knowledge about OpacityMask please share with me. Creating Modern WPF Applications with MahApps.I have used a LinearGradientBrush with Brush transform to implement this.When we are specifying OpacityMask,it won’t consider the color of the brush.Because here the intention is to define an area which is transparent or opaque.But it cares the alpha value very seriously.According to the alpha value only it defines the amount of transparency or opacity.Understanding Distributed Version Control Systems.Understanding and Eliminating Technical Debt.Building Serverless Applications in Azure.Azure Container Instances: Getting Started.Microsoft Azure Developer: Implement Azure Functions (AZ-204).Versioning and Evolving Microservices in ASP.NET Core.Microservices Architecture: Executive Briefing.Microsoft Azure Developer: Deploying and Managing Containers.In fact, it looks to me like it may be the Silverlight rendering that is at fault here rather than WPF.Īnyway, if we combine this information with the blurring of the drop shadow in WPF, we can get a nice gel button in WPF as well. I eventually found that if I changed the bottom gradient stop in the WPF XAML to transparent white instead of transparent black, I got the same appearance as Silverlight. Yuck! I spent a while trying to work out how come the same XAML rendered differently in Silverlight and WPF. Very nice! But now look what exactly the same XAML looks like in WPF: One of the ways you can make your application look great is to add some shapes like circles, triangles and rectangles. Here's what it looks like in Silverlight: Unfortunately, because Silverlight does not support the BitmapEffect property from WPF, we cannot blur this rectangle, so the effect isn't quite as nice as it could be. You can make it smaller using a ScaleTransform, but I found it easier to simply modify the size and corner radius.įinally there is a drop shadow which is a transparent black rectangle (so it appears grey on a white background). This rectangle is marginally smaller than the main rectangle, which gives us a small border. Then there is a transparent highlight rectangle, which goes from white at the top to transparent black at the bottom. In this case, dark green to bright green. The main one goes from a dark colour at the top to a bright colour at the bottom. The basic idea is that you create three rounded rectangles.

I found a nice tutorial on how to create gel buttons using Inkscape, and converted the technique to XAML.
